Product details
Overview
SR1690PT from Taiwan Semiconductor is a 16A, 90V repetitive peak reverse voltage Schottky barrier rectifier in TO-247AD (TO-3P) package, featuring 200A surge current capability, 0.90V typical forward voltage at 8A/25°C, and 100µA max reverse leakage at rated VR and 25°C - used in high-efficiency DC-DC converters and industrial power supplies.
For engineers reviewing the SR1690PT datasheet, SR1690PT pinout, SR1690PT application, or SR1690PT equivalent, key selection criteria include VRRM=90V, IF=16A, VF=0.90V @8A, IFSM=200A, TJ max=150°C, and TO-247AD thermal performance (RθJC=3°C/W).
Technical Context
This dual-die Schottky rectifier operates with low conduction loss and fast switching recovery due to its metal-semiconductor junction. It supports continuous forward current up to 16A with thermal derating above 25°C case temperature and maintains stable reverse blocking up to 90V VRRM.
The device delivers 100µA max reverse leakage at 25°C and 5mA at 125°C, enabling reliable operation in thermally demanding environments. Its TO-247AD package provides robust mechanical mounting (1.13 N·m max torque) and UL 94V-0 flammability compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 90 V - maximum repetitive reverse voltage the device blocks without breakdown |
| IF | 16 A - continuous average forward current rating under specified thermal conditions |
| IFSM | 200 A - non-repetitive peak surge current tolerance for 8.3ms half-sine wave |
| VF @8A, 25°C | 0.90 V - forward voltage drop determining conduction loss in high-current paths |
| IR @90V, 25°C | 100 µA - reverse leakage current affecting standby power and voltage hold-up |
| RθJC | 3 °C/W - junction-to-case thermal resistance enabling efficient heatsink coupling |
| TJ max | 150 °C - maximum allowable junction temperature for rated operation |
Pinout & Package
TO-247AD (TO-3P) package with three terminals: Anode (pin 1), Cathode (pin 2), and case-connected cathode tab (pin 3). The metal tab serves as both thermal path and electrical cathode connection; polarity is marked on the device body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input current terminal | Connects to unregulated input rail; must withstand full surge current and reverse recovery stress |
| Cathode | Output current terminal | Common output node; electrically and thermally tied to metal tab for low-inductance return path |
| Metal tab | Cathode & thermal interface | Provides primary heat dissipation path to heatsink; requires insulated mounting if chassis ground isolation is needed |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring structure | Enhances edge termination reliability and prevents premature avalanche breakdown under transient overvoltage |
| AEC-Q101 qualification option | Supports automotive-grade reliability requirements when ordered as SR1690PTH (not standard SR1690PT) |

IC Role / Device Role / Timing Role: High-efficiency output rectifier handling pulsed load transients up to 200A peak. Use Value: 200A IFSM rating sustains repeated inrush events without degradation, extending field life in consumer electronics. | Use Scenario: +12V output rectification in redundant 2kW server PSUs requiring >96% efficiency and 150°C junction operation. IC Role / Device Role / Timing Role: Thermally robust rectifier mounted directly to aluminum chassis for passive cooling. Use Value: RθJC = 3°C/W enables 16A continuous operation at ≤85°C case temperature, eliminating need for active fans. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-16CTQ090 | Same VRRM (90V), IF (16A), TO-247AC package; VF = 0.82V @8A (lower), RθJC = 2.5°C/W (better) | Higher efficiency at light loads; tighter VF distribution across batch | Preferred where <0.85V VF and sub-2.8°C/W thermal resistance are critical |
| ON Semiconductor MUR1690CT | 90V VRRM, 16A IF, but ultra-fast recovery (not Schottky); VF ≈ 1.25V @8A, higher switching loss | Used where reverse recovery Qrr must be minimized despite higher conduction loss | Select only if EMI constraints require slower dV/dt or if Schottky leakage is unacceptable |
Compared with VS-16CTQ090 and MUR1690CT, SR1690PT offers balanced trade-offs: moderate VF (0.90V), proven TO-247AD thermal interface, and broad industrial qualification - making it optimal for cost-sensitive, thermally constrained 90V rectification where leakage <100µA at 25°C is acceptable.

FAQ
What is the maximum junction temperature rating for SR1690PT?
The SR1690PT has a maximum junction temperature (TJ max) of +150°C, validated per absolute maximum ratings in the official TSC datasheet Version J2103. This rating applies under continuous operation with proper heatsinking and accounts for thermal derating curves shown in Figure 1. Operation beyond 150°C risks irreversible parametric shift or failure. Always verify actual TJ using RθJC = 3°C/W and measured case temperature in final design.
Does SR1690PT have AEC-Q101 qualification?
The standard SR1690PT is not AEC-Q101 qualified; however, the variant SR1690PTH (with 'H' suffix) is explicitly listed in the ordering table as AEC-Q101 qualified. SR1690PT shares identical electrical and thermal specs but lacks automotive-grade reliability testing documentation. For automotive applications, specify SR1690PTH and confirm qualification status via TSC's official automotive product documentation.
What is the forward voltage specification for SR1690PT at 16A?
The SR1690PT datasheet specifies forward voltage only at IF = 8A (VF = 0.90V typ, 25°C), not at 16A. At full-rated 16A, VF increases nonlinearly due to series resistance and self-heating; typical values exceed 1.05V. Designers should use the provided VF vs. IF curve (Figure 4) and apply thermal derating based on actual case temperature to determine real-world conduction loss at 16A.
Is SR1690PT compatible with lead-free reflow soldering processes?
Yes, SR1690PT features matte tin-plated leads compliant with J-STD-002 for solderability, and its TO-247AD molding compound meets UL 94V-0 flammability rating. The device supports standard lead-free reflow profiles (peak temp ≤ 260°C, 10s max), provided preheat and soak phases respect JEDEC J-STD-020 moisture sensitivity level (MSL) - though TSC does not assign an MSL rating to this through-hole power device.
What is the reverse leakage current of SR1690PT at 125°C?
Per the Electrical Specifications table in TSC's SR1620PT–SR16150PT datasheet (Version J2103), SR1690PT exhibits ≤5 mA reverse leakage current (IR) at rated VRRM = 90V and TJ = 125°C. This value is measured under pulse conditions (PW = 30ms) and reflects worst-case thermal stress in high-temperature operation - critical for standby power budgeting in energy-efficient designs.
